core: Add ffa_msg_send_req and ffa_msg_send_resp

Add FF-A message handling of FFA_MSG_SEND_DIRECT_REQ_32 and
FFA_MSG_SEND_DIRECT_RESP_32 messages.
The FFA_MSG_SEND_DIRECT_RESP_32 message is used to send a message from
one FF-A endpoint to a second FF-A endpoint. FFA_MSG_SEND_DIRECT_RESP_32
is used to send a response message from the callee to the caller.

A separate abstraction is made (spmc_sp_handler) for handling FF-A
messages received from secure endpoints (SP).
thread_spmc_msg_recv() is still used for handling all FF-A messages
coming from the Normal World. When a FFA_MSG_SEND_DIRECT_REQ_32 message
is received for the Normal World a new kernel thread is started and
spmc_sp_msg_handler() is run. spmc_sp_msg_handler() is used as the main
message handler for handling the FF-A messages coming from SPs.

Whenever a message is sent to the normal world the thread is finished
and the FF-A message is forwarded to the Normal World.

Whenever a SVC exception is received from an SP, the whole context is
saved and executions is resumed in S-EL1. The first 8 register (FF-A
registers x0-x7) contain the FF-A message and are used to handle the
message by the SPMC.

build: core: add missing dependencies when generating assembly constants

The header file <generated/asm-defines.h> is created at build time. It
contains macro definitions for various offsets in C structures and is
especially useful for use from assembler code. It is generated from
asm-defines.c, which includes a number of header files, of which two
are also generated at build time: <generated/arm32_sysreg.h> and
<generated/arm32_gicv3_sysreg.h>.

These dependencies are expressed nowhere in the makefiles and therefore
build errors can result. For example:

$ make out/arm-plat-vexpress/core/include/generated/.asm-defines.s
CHK out/arm-plat-vexpress/conf.mk
UPD out/arm-plat-vexpress/conf.mk
CHK out/arm-plat-vexpress/include/generated/conf.h
UPD out/arm-plat-vexpress/include/generated/conf.h
CC out/arm-plat-vexpress/core/include/generated/.asm-defines.s
In file included from core/arch/arm/include/arm.h:99,
from core/arch/arm/include/kernel/thread.h:12,
from core/arch/arm/kernel/asm-defines.c:8:
core/arch/arm/include/arm32.h:167:10: fatal error: generated/arm32_sysreg.h: No such file or directory
167 | #include <generated/arm32_sysreg.h>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

The error in [1] is believed to have the same root cause: during
parallel build the generated header file might have been created by one
job but not yet written to when another job would open it. The compiler
would see an empty file, thus the missing declarations.

Add the missing dependencies via a new variable at the location where
asm-defines.c is added to the build.

Note that the other core .c files depending on these generated sysreg
headers are not affected because their .o files explicitly depend on
FORCE-GENSRCcore (which generates the headers).
